Yac's outing the other day was a snapshot of the whole staff so far. He actually looked liked he had good stuff at the start, then gave up the first blast, got pissed, totally ignored the catcher, looking for locations, and tried to blow the ball by the hitters and paid for it by allowing two long home runs including one to Jason Castro, who is not known for his power.

He's a very replaceable guy, and there is plenty of competition for spots on the way.

He has two months to show he can get ML hitters out and be in position to compete for a spot on the ML roster next spring.

He does have some arm talent. Not just velocity but movement and deception.

But the results haven't been good enough, and he is in danger of just being passed by.

If he is capable of making adjustments, need to see them now. He has the arm talent to be an opener or follow an opener...and youd like him to be a guy that could give your more innings vs typical relievers..but he has to perform.
